* Uw-h IMPROVEMENT IN'Y GAS-HEATERS.

The Schedule referred to in these Lettere Patent and making part of the same.

To all whom it may concern Be it known that I, A. L. BOGART, of the city, county, and State of New York, have invented certain new and useful Improvements in Gas-Stove Burners and do hereby declare that the following is afull, clear, and exact description of the same, reference being had to they accompanying drawing, making a part of this specilication, in which- Figure 1 represents a perspective view of my im.- proved burner, as applied to the top of a stove;

Figure 2 isa vertical longitudinal section; and

Figure 3 is a plan v iew of the upper side ofthe same.

Letters of like name and kind refer to like parts in each of the figures.

rlhe object of my invention is to furnish a suitable burner for cooking-purposes, which 'can be applied. to the. tops of ordinary cooking-stoves, upon mantels, 86o., without requiring openings in said articles for the passage of the pipes for conveying gas to the burner.

Iteonsists in the form and arrangement of a horizontal chamber-burner, secured to a vertical pipe, used as a mixing-chamber, so that when said pipe is placed against the side of a stove the burner shall extend inward upon the top thereof', so as to bring the centre of thel flame of gas in'nnediately over the ordinary boiler-holes, by which means the same stove used for burning coal or wood in winter, when much heat is required, may be changed to a gas-stove in summer, at but a trifling expense, and with no alteration of any of its parts.

In the annexed drawing- A represents a fiat, hollow chamber, forming the burner, in the form shown, the yinner end being enlarged so 'as to give the-required size for the burner, and provided upon its upper side with perforations,

a a, dec., for the escape of the gas, while the outer I end has sufficient size only to enable it to receive the upper end. of the-mixing-chamber or pipe, B. The pipe B is secured to the burner A at a righ angle with its face, so that when. said burner is placed upon the top of a stove or other horizontal surface, the pipe shall extend downward, vertically.

This burner is more especially designed for use upon ordinary cooking-stoves,"although applicable in many other places.

When applied to a stove, it is-intended that the burner shall be of such a length as to bring the centre of the perforations, and, consequently, of the flame, directly over the centre of the boiler-hole, when the vertical pipe B ispiaced against the side of said stove, where it may be secured by any'means deemed best.

When thus placed, and the nipple C at the lower end of the mixing-chamber, connected by a rubber tube, or other means, with the gas-pipes, the gas being admitted thereto passes upward from the nipple, carrying with it a sufficient quantity of air to insure its perfect combustion as it leaves the burner through the perforations.

In order that the heat of the burning gas may be little above the stove-top, and, consequently, does not inconveniently change their position.

The advantages possessed by this burnerare many,

and hardly require enumeration. By its use an ordinary coal or wood-stove can be converted into a gasstove of equal capacity, at but'a trifling expense, and without the slightest change of any of its parts, as the supply-pipes. are arranged against the sides of said stove, instead of passing upward through the plates beneath the burner, as is required in applyngother burners. l

The use of this apparatus also avoids the necessity of removing stoves in the summer, a labor of difculty, from their size and weight, and a matter of inconvenience nom the want of a suitable place for storage.

The cooking-stove` is usually in the handiest place in the house for the purposes of cooking, and by mak? ing use of it as a base for my apparatus, Iv obtain all the conveniences of locality, and by placing my burner over the boiler-holes, I avoid the annoyance of some portion of the heat.

Again, the addition of the mixing-chamber insures the union with the gas of a suilicient supply of air to render certain its perfect combustion, so that the perforations for its. escape from vthe burner may be of any desired capacity, without producing a smoky llame, by which means one of the greatest objections to the use of ordinary burners, (the liability of the perforations to become closed by dirt, grease, &c.,) is entirely removed.

In vpoint of construction, my burner has the advantagesofeheapnes's, being cast in one piece; of strength, having arching forms tol its sides; and of economy of l space, being most nearly conformable to the shape of cooking-utensils, and tothe boiler-holes in stoves.

I ani aware that `many forms of gas-burners -for cooking-purposes have been patented by Pettitt and Smith, in their English patent No. 193,4 dated January 24, 1856, and I hereby disclaim the use of any of the same.

Having thus fully set forth the nature and merits of my invention,

What I claim as new, and desire to secure by Letters Patent, is-

As a new. article of manufacture, the within-described gas-stove burner A, with its mixing-chamber B, the whole device constructed and arranged to operate substantially as and for the purpose shown.
